The oxygen sensor is controlled by the Smart Oxygen Module (smart O2 module). This module is a smart device that receives information, such as dew point flag, engine speed, etc., from the primary engine Electronic Control Module (ECM). It provides ECM with the oxygen concentration signal. It also performs its own diagnostics and reports failures back to the primary engine ECM. The ECM then decodes the error message and converts it to a fault code.
